Should I Add My Guppies To My Large Molly Tank?

HI all,
I have a 5-gallon tank I've had for a few months now, fully planted tank with neo shrimp, snails, 4 beautiful male fancy guppies, and 2 healthy growing guppy fry (my female guppies managed to birth two before I returned them to the store in exchange for males only, and the males haven't bothered the babies :joyful.

I also recently got a 55-gallon, and I have 2 red sailfin mollies (1m/1f) and 3 dalmatian lyretail mollies (1m/2f), still juveniles, I think two maybe pregnant. I've had them a few days and they look healthy. The sailfins are very outgoing from the start and the dalmatians spent the first 2 days hiding (from me, they don't mind the sailfins ) but are now starting to explore more.

I was thinking...should I put the 4 male guppies in with the mollies to enjoy the new large tank...or maybe it's not a good idea?
The male guppies are friendly together but would they start harassing my female mollies because they are "sex-starved" in their single-gender tank? I don't want hybrid guppy-molly babies. Or would female mollies not let the guppies do that since they already have male mollies to do that with?
Also, would the 2 male mollies get ticked off and go after my guppies? They are not aggressive currently.
What would you do? Have you had male + female mollies with only male guppies and did the mollies still end up mating with the guppies?

Sorry if it's a lot of questions! I can't decide.

 

Some people mix them without issue though they can hybridize.

You could always up the ratio of females and maybe add female guppies too... it should be 2 females for every 1 male ideally.

 

What I have heard is if mollies outnumber guppies they usually get beat up but it is worth the shot every fish is different just watch to see if any aggression starts

 

Thanks for the feedback!
I put the male guppies in with the mollies and didn't see any aggression.
The next day the male guppies were acting interested in the female mollies - only the dalmatian male molly tried to defend his gals, but he didn't try very hard and then lost interest.
So I went to my LFS and got 5 female guppies. They all seem happy now, guppies dancing around each other, mollies mostly exploring and foraging (less shy now). Watching them is very entertaining, I didn't expect them to all be so friendly

Another type of fish I'd love to add in the future is a couple of gouramis...not now, once the tank is done being planted. Can anyone recommend gourami for a 55 gallon with mollies/guppies, what type does best in a community with livebearers?

 

Honey gouramis would be your best option... or maybe sparkling gouramis

 

Yep

 

Thanks, also I forgot to mention I don't mind that whatever I add in the tank will eat the guppy and molly fry (I assume that it will start getting overrun sooner or later).
Will the gold/sparkling gouramis eat fry? What about tetras?
